ROTARY SHOE-IBEATING MACHINE.

Application fired June 25,

Specification of Letters Patent.

Patented Dec. 31, 1912.

1912. Serial No. 705,725.

b all whom it may concern:

Be it known that I, ()nunLL Asn'roN, a citizen of the United States,residing at Swampscott, in the county of Essex and State ofMassachusetts, have invented certain Improvements in Rotary Shoe-BeatingMachines, of which the following description, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This inventi'on relates to'rotary pounding machines of the type shown inLetters Patent of the United States No. 1,030,837, granted June 25,1912, on my earlier application, Ser. No. 4t06,213, filed Dec. 12, 1907, which comprise a rotary carrier and beating members arranged aboutthe periphery of the carrier, each member consisting of one or morerings loosely mounted on the carrier to permit them to turn and also toyield toward the axis of the carrier against centrifugal force. I havefound by experiment that such loose rings if eccentrically bored so thatthey are held by centrifugal force with theheavier sides outward willstrike a heavier blow than concentric rings will strike and that theeffectiveness of the blow is further increased by the fact that theeccentric rings both yield inwardly and also turn backwardly lessquickly or readily when they strike the work. They therefore cause adrawing or a dragging action over the work to a greater extent and lessof a rolling action. This is probably because centrifugal force isoperating continuously, while'the eccentric ring is passing over thework, to turn the rollback to the position in which its heavier side isoutermost. I have also found it advantageous to mount the rings to havecapacity for a slight lateral tipping movement for adapting themselvesto transverse irregularities in the work.

The invention will now be described in connection with the accompanyingdrawings and then be particularly pointed out in the claims.

Figure 1 shows in vertical section so much as is necessary for theunderstanding of this invention of a machine of the type of my earlierpatent equipped in accordance with this prevent invention. Fig. 2 is afragmentary front view.

The rotary carrier 2, driven as usual, has

end plates 3 between which extend rods 4 on which the beating rings 5are strung. The beating rings are bored eccentrically and to permitradial play on the rods so that the eccentric rings are turned and alsopressed radially outward by centrifugal force when the carrier is inmotion as indicated by the position of the rings which are approachingthe work in Fig. 1. Each ring then strikes the work with the weight ofits heavier outer side, which is less than balanced by its inner side,and upon striking the work turns as well as yields inwardly against theresistance of this weight which centrifugal force tends to bring back tooutermost position as the ring drags over the work the surface of whichis usually approximately tangential to the path of the rings moving withthe carrier. The inner edges of the rings formed by the eccentric boringare also preferably beveled as at 6 to permit the rings to have alimited lateral tipping movement for better adaptation to irregularitiesin the surfaces over which they pass.

Having explained the invention, I claim as new and desire to secure byLetters Patent of the United States 1. In a machine of the classdescribed a shoe beater con'iprising a rotary carrier and beatingmembers arranged about the periphery of the carrier, each memberconsisting of a plurality of eccentrically bored rings loosely mountedon the carrier.

2. In a machine of the class described a shoe beater comprising a rotarycarrier having an annular series of pivot rods and cocentrically boredrings loosely hung on the rods to have radial. play, substantially asdescribed.

3. In a machine of the class described, a rotary shoe beater comprisinga carrier, an annular series of rods therein and an annular series ofbeating members on said rods in the form of rings having larger interiordiameters than the rods whereby they may be moved bodily outwardly bycentrifugal force when the carrier is rotated, said rings beingeccentrically bored whereby their heavier sides are turned back tostriking position by said force after each passage over the work.

4. In a machine of the class described a shoe beater comprising a rotarycarrier and beating members arranged about the periphname to thisspecification in the presence of ery of the carrier, each memberconslstlng two subserlolng \vltnesses.

of a plurality of rings loosely mounted on the carrier to have radialplay and having ORRELL ASHTON their inner edges beveled to permit oflim- I Witnesses: ited lateral tipping movement. JENNIE P. ANDERSON,

In testimony whereof I have signed my MARTHA W. COUPE.
